Remark 0.3 Let us also point out that the role of \(\lambda _1^*\)  in Theorem REF  is quite different from the one it played in [1]}. There the lower bound \(\lambda _1^*>2\)  is used to rule out the existence of irreducible solutions to the Seiberg-Witten equations. In the present paper the assumption \(\lambda _1^*\ge \delta \)  will be used instead to provide a priori bounds on their norm, and our arguments will not tell us anything about the number of solutions (which is possibly zero in certain cases).
